Pressure-Regulating Valves

Pressure-Regulating Valves for
Water, Oil, Air, and Inert Gas

Pressure-Regulating Valves for Water, Oil, Air, and Inert Gas

Install these valves in pipelines.

Panel-Mount Pressure-Regulating
Valves for Water, Air, and Inert Gas

Threads below the handle and an included panel-mount nut let you install these valves in your instrument panel.

Back-Pressure-Regulating Valves

Usually installed at the end of a pipeline, these valves obstruct flow to maintain sufficient operating pressure for upstream equipment.

Other Control of Liquids, Gases, and Solids

Pressure-Relief Valves

Automatically open at a set point to relieve excess pressure and protect tanks, pipelines, and equipment. These valves are available in relief and pop-safety styles.

Pressure-Relief Airlocks

On containers filled with water, these airlocks create a liquid seal that keeps contaminants out while letting gases produced by chemical reactions and temperature changes escape. They’re common in fermentation applications, such as beer brewing and winemaking.

Flow-Control Valves

Flow-Control Valves

Start, stop, adjust, and direct flow or prevent backflow.

Flow-Control Orifices

Also known as flow restrictors and precision orifice valves, these are used to throttle, vent, bleed, or regulate the flow of liquid and gas.

Flow Switches

Flow Switches

Activate and deactivate equipment when the flow rate reaches your set point.

Flow Transmitters for Water

Flow Transmitters for Water

Flowmeters for Water

High-Temperature
Totalizers for Water

Withstand temperatures of at least 194° F.

Flowmeter/Totalizers for Water

Flowmeter/Totalizers for Water

NPT connections are for use with threaded pipe.

Remote-Reading
Temperature-Regulating Valves

An external sensor opens and closes the valve based on temperature changes in your tank or pipeline.

Laboratory Valves

default

Hose Fittings

Connect these fittings to lengths of hose. Hose fittings are typically used in high-flow, suction, and hydraulic applications.
